| Outline of Final Research Achievements |
The relation between applied strain and the fracture of organic thin films for organic semiconductors was studied to evaluate the ductility of the films. As a result, it was found that the Alq3 films had good ductility and the ductility of α-NPD thin films were improved by mixing Alq3. In addition, BAlq, TNATA, HAT-CN, CBP and NPB, which are typical materials for OLED were also examined. Then, a new device structured with better ductility has proposed by replacing the low critical strain layers. Furthermore, reduced elastic moduluses of organic luminescent materials deposited on a glass substrate were measured by nano-indentation techniques to understand mechanical properties of the thin films for organic light emitting diode (OLED) to design flexible OLED and to produce by roll-to-roll manufacturing process.
